Construction of copper-based coordination polymers with 1D chain, 2D plane and wavy networks: Syntheses, structures, thermal behavior and photoluminescence properties

Three Cu-based coordination polymers (CPs), including [Cu II(N- eta 1-NCS) 2(O- eta 1-DMF) 2(mu 2-3,3′-bptz)] n (1), [Cu I(1,3- mu 2-NCS)(mu 2-3,3′-bptz)] n (2) and [(Cu I(1,3- mu 2- NCS))(mu 2-4,4′-bptz)] n (3) (DMF = N, N-dimethyl formamide, 3,3′-bptz = 3,6-bis(3-pyridyl)tetrazine and 4,4′-bptz = 3,6-bis(4-pyridyl)tetrazine) have been successfully constructed by solution diffusion reactions by using Cu(NO 3) 2.3H 2O or CuNCS and KNCS with 3,3′-bptz / 4,4′-bptz ligands, respectively. The resulting crystalline materials have been characterized by the single-crystal X-ray diffraction analyses, elemental analyses, FT-IR spectra, thermogravimetric analyses and powder X-ray diffraction (PXRD). Single crystal X-ray analyses revealed that CP 1 is organized in one-dimensional (1D) chain in which the Cu(II) ions are coordinated by eta 1-NCS – anions and eta 1-DMF molecules, and linked by mu 2-3,3′-bptz bridging ligands. CPs 2 and 3 are structural isomers. CP 2 exhibits two-dimensional (2D) (4,4)-plane-like network in which Cu(I) ions are linked by mu 2-NCS – and mu 2-3,3′-bptz ligands. In CP 3, Cu(I) ions are connected by mu 2-NCS – and mu 2-4,4′-bptz ligands to form 2D saw-tooth wavy network. In addition, the photoluminescence properties of CPs 1-3 were also investigated in the solid state at room temperature.

One-pot synthesis of CuInS2 nanocrystals using different anions to engineer their morphology and crystal phase

A simple one-pot colloidal method has been described to engineer ternary CuInS2 nanocrystals with different crystal phases and morphologies, in which dodecanethiol is chosen as the sulfur source and the capping ligands. By a careful choice of the anions in the metal precursors and manipulation of the reaction conditions including the reactant molar ratios and the reaction temperature, CuInS2 nanocrystals with chalcopyrite, zincblende and wurtzite phases have been successfully synthesized. The type of anion in the metal precursors has been found to be essential for determining the crystal phase and morphology of the as-obtained CuInS2 nanocrystals. In particular, the presence of Cl- ions plays an important role in the formation of CuInS2 nanoplates with a wurtzite-zincblende polytypism structure. In addition, the molar ratios of Cu to In precursors have a significant effect on the crystal phase and morphology, and the intermediate Cu2S-CuInS2 heteronanostructures are formed which are critical for the anisotropic growth of CuInS2 nanocrystals. Furthermore, the optical absorption results of the as-obtained CuInS2 nanocrystals exhibit a strong dependence on the crystal phase and size.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13395-16-9 is helpful to your research. Computed Properties of C10H16CuO4

Annealing Solution-Processed CuSCN Hole Injection Layer for Blue Phosphorescent Organic Light-Emitting Diodes with Extremely Low Efficiency Roll-Off

Phosphorescent organic light-emitting diodes (PhOLEDs) have attracted tremendous attention recently but still suffer serious efficiency roll-off at high luminance, which will significantly limit their practical application in the future. Here, using a spin-coated transparent CuSCN film as the hole-injection layer (HIL), we succeed in achieving high-performance blue PhOLEDs with extremely low efficiency roll-offs based on widely used host and guest materials in a conventional device structure; by thermal and current annealing treatments, the external quantum efficiency (EQE) is up to 12.5% at 8370 cd m-2, and the EQE roll-off can be as low as 2% at 10 000 cd m-2 and 7% at 20 000 cd m-2, respectively. The inorganic molecular semiconductor feature of CuSCN and the improved hole mobility after the annealing treatment were proved to be the main reasons for the highly stable PhOLEDs. The successful application of solution-processed CuSCN HIL for blue PhOLEDs with low efficiency roll-offs could provide important guidelines for the development of low-cost and highly efficient devices at high luminance.

Network Motifs and Thermal Properties of Copper(I) Halide and Pseudohalide Coordination Polymers with 1,7- and 4,7-Phenanthroline

The coordination polymers .infin.(1)[CuBr(1,7-phen-kappaN7)] (1a), [CuI(1,7-phen)] (2a) and [(CuI)2(1,7-phen-kappaN7)] (2b) may be prepared by treatment of the appropriate copper(I) halide with 1,7-phenanthroline(1,7-phen) in acetonitrile. 1a exhibits staircase CuBr double chains, 2 a novel quadruple CuI chains. Their thermal properties were investigatedby DTA-TG and temperature resolved powder X-ray diffraction. On heating , both 1:1 compounds decompose to 2:1 polymers and then finally to CuBr or CuI. With 4,7-phenanthroline (4,7-phen), CuBr affords both 1:1 and 2:1 complexes (5a, 5b), CuI 1:1, 2:1 and 3:1 complexes (6a, 6b, 6c) in acetonitrile at 20¡ãC. 5a and 6a display lamellar coordination networks, with the former containing zigzag CuBr single chains, the latter 4-membered (CuI)2 rings. A second 2:1 complex .infin.(2)[(CuI)2(4,7-phen-mu-N4,N7)] (6b’) with staircase CuI double chains can be obtained by reacting CuI with 4,7-phen in a sealed glass tube at 110¡ãC. Both 5a and 6a exhibit thermal decomposition pathways of the general type 1:1 2:1 3:1 CuX, and novel CuX triple chains are proposedfor the isostructural 3:1 polymers 5c and 6c. X-ray structures are repo rted for complexes 1a, 2b, .infin(2)[(CuCN)3(CH3CN)(1,7-phen-mu-N1,N7)] (3c*CH3CN), .infin.(1)[CuSCN(1,7-phen-kappaN7)] (4a), 5a, 6a and .infin.(2)[CuCN(4,7-phen-mu-N4,N7)] (7a).

Linear and cyclic tetranuclear copper(I) complexes containing anions of N,N?-bis(pyrimidine-2-yl)formamidine

The reaction of Kpmf (pmf = anion of N,N?-bis(pyrimidyl-2-yl) formamidine, Hpmf) with CuSCN afforded the complexes K[Cu4(pmF) 3(SCN)2], 1, and Cu4(pmf)4, 2. Reaction of 1 with [(n-Bu)4N]PF6 in THF gave the complex [(n-Bu)4N][Cu4(pmf)3(SCN)2], 3. Their structures were characterized by X-ray crystallography. Complexes 1 and 3 are the first linear tetranuclear complexes containing only Cu(I) atoms, while complex 2 is cyclic. The four Cu(I) atoms of complexes 1 and 3 are helically bridged by three tetradentate pmf- ligands. The [Cu 4(pmf)3(SCN)2]- anions of 1 show weak interactions with adjacent [K(THF)5]+ cations through the sulfur atoms, forming infinite chains which are subjected to a series of intermolecular pi-pi interactions. In complex 2, the pmf- ligands are coordinated to the copper atoms in bidentate fashion through the two central amine nitrogen atoms, leaving the pyrimidine nitrogen atoms uncoordinated. Unexpected fluxional behaviors were observed for complexes 1 and 3 in solution. By the DNMR analysis, the free energy of activation (DeltaGc?) for the exchange is 12.8 kcal mol-1 at 278 K (Tc), and the rate constant of exchange (Kc) is 470 s-1 for 1. The DeltaGc? and Kc are 12.6 kcal mol-1 at 273 K and 433 s-1, respectively, for 3. The Royal Society of Chemistry 2005.

Wavelength dependent photochemical charge transfer at the Cu2O-BiVO4 particle interface-evidence for tandem excitation

The understanding of the photochemical charge transfer properties of powdered semiconductors is of relevance to artificial photosynthesis and the production of solar fuels. Here we use surface photovoltage spectroscopy to probe photoelectrochemical charge transfer between bismuth vanadate (BiVO4) and cuprous oxide (Cu2O) particles as a function of wavelength and film thickness. Optimized conditions produce a -2.10 V photovoltage under 2.5 eV (0.1 mW cm-2) illumination, which suggests the possibility of a water splitting system based on a BiVO4-Cu2O direct contact particle tandem.

Electrochemical self-assembly of CuSCN-DAST hybrid thin films

Abstract: Nanostructured inorganic?organic hybrid thin films of copper(I) thiocyanate (CuSCN) and 4-(N,N-dimethylamino)-4?-(N?-methyl)stilbazolium tosylate (DAST) were electrochemically self-assembled by adding DAST into methanolic bath containing Cu2+ and SCN? ions. Loading of the stilbazolium organic chromophore (DAS+) increased linearly on increasing DAST concentration, accompanied with changes of the film morphology, crystallographic orientation of CuSCN and transition from beta- to alpha-CuSCN. At low DAST concentrations, transport limited passive occlusion of DAS+ has been suggested with its diffusion coefficient of 1.25?¡Á?10?6 cm2?s?1 in methanol at 298?K, while the loading receives kinetic limitation by the surface chemical reaction to yield definitive hybrid structures, resulting in unique ?hair comb? shape beta-CuSCN-DAST and ?nano-platelets? shape alpha-CuSCN-DAST hybrid structures. Both the inorganic and organic components are interconnected and bi-continuous, as the loaded DAS+ could be totally extracted by dimethylacetamide to leave porous skeleton of crystalline CuSCN, making them highly interesting for device applications.
